Stick up cam 3rd gen will not connect to existing chimes

I’ve had 3 ring cameras for years and two first gen chimes. All working fine. Recently I’ve bought two 3rd gen stick up cameras, they have all connected fine and are working, but I can’t get them to connect to my chimes. When clicking ‘linked chimes’ I just get ‘hmm something went wrong, please try again later’ All my existing cameras are fine and connected to the chimes Troubleshooting so far; Rebooted new cameras Re-added chimes Re-booted rooter Checked all settings Has anyone else had this? Is it a compatibility issue between the 3rd gen camera and the old chimes?
